Chapter 6 Deploying Wireless Networks for FortiOS 5.0 : Support for location-based services : Configuring location tracking
  
Configuring location tracking
You can enable location tracking in any custom AP profile, using the CLI. For each radio, set the station-locate field to enable. For example:
config wireless-controller wtp-profile
edit "FAP220B-locate"
set ap-country US
config platform
set type 220B
end
config radio-1
set station-locate enable
end
config radio-2
set station-locate enable
end
end
